The T8850C is a 40‑channel Field Termination Assembly (FTA) from ICS Triplex‘s Trusted series, engineered as the primary physical interface between Trusted TMR output modules and field actuators in safety instrumented systems. The T8850C is the enhanced variant of the standard T8850, featuring a conformal‑coated PCB (IPC‑610‑3C) for 5× salt‑fog life, making it ideal for harsh environments such as offshore platforms, chemical plants, and coastal installations. The T8850C provides 40 output channels arranged in five isolated groups of eight, supporting both analogue (4–20 mA) and digital (24 Vdc) signals. Compatible with T8451, T8461, and T8480 output modules, the T8850C features a fuse‑free design with electronic protection, SmartSlot hot‑swap capability, and on‑board LED power status indication.
Mounting – Install the T8850C on a standard TS32 or TS35 DIN rail in horizontal or vertical orientation as required. Ensure the mounting clips are fully engaged for physical stability.
Module Connection – Connect the Trusted output module (T8451, T8461, or T8480) to the FTA via a dedicated SmartSlot or Companion Slot cable. The FTA routes signals from the output module to the connected field devices.
Field Wiring – Connect field devices (valves, solenoids, actuators, indicators) to the terminal blocks using 2‑wire connections. Screw‑clamp terminals accept 12–28 AWG wire.
Power Supply – Connect dual 24 Vdc field power feeds. The assembly supports up to 60 Vdc maximum when powered via T8290 configuration. Each of the five isolated groups receives independent power.
0V Reference – The 0V connection at the FTA end allows the module to measure its output voltage; connect this to the field 0V supply.
LED Indication – On‑board green LEDs provide visual status of field power integrity for each power group.
Hot‑Swap – SmartSlot support enables replacement of output modules without disconnecting field wiring or system shutdown.
40 High‑Density Output Channels – Supports up to 40 output field loops in a single FTA, maximising cabinet space efficiency.
Five Isolated Power Groups – Each group of 8 channels is independently isolated (50 V reinforced), preventing cross‑group interference and containing faults.
Fuse‑Free Design – Electronic overcurrent protection eliminates fuse replacement, reducing maintenance downtime.
Dual Purpose Analogue/Digital Support – Compatible with both digital output modules (T8451, T8461) and analogue output modules (T8480).
SmartSlot Hot‑Swap Capability – Enables “one to many” online replacement of output modules without rewiring field cables.
Conformal Coating (C Variant) – IPC‑610‑3C chemical‑grade conformal coating protects circuitry from moisture, dust, salt fog, and toxic gases.
Configurable Over‑Voltage Protection – Group‑level OVP configurable via TriStation 1131 (28V, 32V, 36V trip points).
Standard DIN Rail Mounting – Compatible with TS32 or TS35 rails, horizontal or vertical installation.
On‑Board LED Indication – Provides visual field power status for each channel group, simplifying troubleshooting.
SIL‑3 Certified – Meets IEC 61508 SIL‑3 safety integrity requirements.
The T8850C functions as a passive termination and signal distribution hub between the Trusted TMR output module (T8451, T8461, or T8480) and field actuators. It performs no active logic processing—that function resides in the Trusted output module itself. Instead, the T8850C provides the physical interface for field wiring, power distribution, and signal routing.
The 40 output channels are grouped into five isolated banks of eight channels each. Each group receives independent field power, with individual electronic protection rather than fuses. This group isolation ensures that a short circuit or overcurrent fault on one channel is contained within that group and does not affect other groups or the system logic.
Signals from the Trusted output module are transmitted to the T8850C via a dedicated SmartSlot or Companion Slot cable. The FTA routes these signals to the connected field devices, ensuring proper distribution and integrity of the output signals. The field power return (0V) connection at the FTA provides a reference for the output module to measure its output voltage.
The “C” suffix indicates an enhanced version with chemical‑grade conformal coating treatment, effectively isolating the circuitry from moisture, dust, and toxic gases commonly found in harsh factory environments. This makes the T8850C suitable for offshore platforms, coastal installations, and chemical processing plants where standard FTAs would be susceptible to corrosion.
On‑board LEDs indicate field power integrity for each group, enabling rapid visual fault diagnosis. The SmartSlot interface supports hot‑swap replacement of output modules without disconnecting field wiring, minimising downtime during maintenance. The T8850C is designed to meet SIL‑3 safety integrity requirements, making it suitable for emergency shutdown (ESD), fire & gas (F&G), and burner management systems (BMS).
Q1: What is the difference between the T8850 and the T8850C?
A1: The T8850C is the enhanced variant of the standard T8850. It features a conformal‑coated PCB (IPC‑610‑3C) providing 5× salt‑fog life, making it ideal for harsh environments such as offshore platforms, coastal installations, and chemical plants. The T8850C also offers configurable group‑level over‑voltage protection (28V, 32V, 36V) via TriStation 1131.
Q2: Which output modules are compatible with the T8850C?
A2: The T8850C is compatible with the T8451 (24 Vdc digital output), T8461 (24/48 Vdc digital output), and T8480 (analogue output) Trusted TMR modules.
Q3: How many channels does the T8850C provide and how are they arranged?
A3: The T8850C provides 40 output channels, arranged in five isolated groups of eight channels each.
Q4: Does the T8850C require fuse replacement in case of a short circuit?
A4: No. The T8850C uses a fuse‑free design with electronic overcurrent protection. There are no physical fuses to replace, reducing maintenance downtime.
Q5: What is the maximum field supply voltage supported by the T8850C?
A5: The T8850C supports up to 60 Vdc maximum when powered via T8290 configuration.
